“I recovered a robot from a basement in Islington from a wonderful company called Shadow, who make robotic hands. I went to see them and at the end of the visit they mentioned ‘oh we’ve got a humanoid in the basement’. Oh blimey, why didn’t you tell me sooner!

“We went downstairs, and in a cupboard there was a gaping void where the ceiling had collapsed – plaster and rubbish everywhere – and i ended up dragging this [our Bipedal Walker] out by its ankles. You have to [do these things], it’s the best part of the job!”

Geoff also asked Ben what’s the closest somebody has got to the functionality of a human hand, to which Ben replied:

“A company in London, called Shadow; they’ve built a remarkable piece of micro engineering. Actually the more you look at it, the more you realise how your own hand is amazing. You can do all this stuff with your hand…it’s a miracle if evolution, frankly.

“What was funny with the Shadow Hand – the first one – the acid test for it was ‘would it pick up a pint glass of beer?‘ Even that, you think ‘ that’s simple’ (perhaps after a few beers it isn’t), but just having the fingers positioned, the relative position of the thumb, it’s quite heavy and quite slippery – all of this you balance in your mind without even thinking about when you go and have a beer. Trying to get a robot to do that was a hell of a job – if it doesn’t squeeze enough then it’ll let the glass go, squeeze too much and you break the glass, the parameters are changing continuously. There’s a lovely bit of film we found, a robot hand, it’s quite rudimentary, it picks up a pint! They probably went and had a beer after that.”
